This report provides a summary of the 2013 Slovenian renal replacement therapy (RRT) data, obtained from 24 renal centers: 23 dialysis and one transplant center, referring from 31 December 2013, with 100% response rate to individual patient questionnaires. Slovenia had a population of 2 061 085 on 1 January 2014. The total number of patients treated by RRT was 2077, i.e. 1008.3 per million of population (pmp); 1349 (65%) were treated by hemodialysis, 52 (2.5%) by peritoneal dialysis, and 676 (32.5%) had a functioning kidney graft. A total of 260 incident patients, 126.2 pmp (at day one), started RRT, their median age was 69 years, 59.8% were men,. 58.5% of hemodialysis patients were treated with on-line hemodiafiltration. Vascular access was arteriovenous fistula in 79%, polytetrafluoroethylene graft in 8%, and catheter in 13% of patients, mean blood flow 276 ± 41 mL/min, 5.5% dialyzed in a single-needle mode. The crude death rate was 11.4% in all RRT patients (incident patients day 1 included, 15.9% in hemodialysis, 12.3% in peritoneal dialysis, 2.1% in transplant recipients). 60 kidney transplantations were performed in 2013, from deceased donors.

This report provides a summary of the 2011 Slovenian renal replacement therapy (RRT) data. Data were obtained from 24 renal centers: 23 dialysis and one transplant center, referred as of 31 December 2011, with 100% response rate to individual patient questionnaires. Slovenia has a population of approximately 2 million (2 052 496 in 2011). The total number of patients treated by RRT was 2011,that is, 980 per million of population (pmp); 0.4% decrease compared to 2010. 1347 (67.0%) were treated by hemodialysis, 60 (3.0%) by peritoneal dialysis, and 604 (30.0%) had a functioning kidney graft. A total of 236 incident patients, 115 pmp (at day one), started RRT, their median age was 68 years, 64.8% were men, 36.4% were diabetics. Regarding hemodialysis patients, 59.3% were treated with on-line hemodiafiltration, 86% with ultrapure dialysis fluid. Median weekly duration of hemodialysis was 12.5 h, median dry body weight 70 kg, mean blood flow 275 ± 46 mL/min, 7.1% were dialyzed in a single-needle mode. Vascular accesses were native arteriovenous fistula in 79%, polytetrafluoroethylene graft in 6%, and catheter in 15%. The crude death rate was 15.9% in dialysis patients, 1.9% in transplant recipients, and 12.0% in all RRT patients (both dialysis and transplant, incident patients at day 1 included). Slovenia has been a member of Eurotransplant since 2000. Forty-six kidney transplantations were performed in 2011, all from deceased donors. A slight decrease in prevalent number of RRT patients was observed in 2011, for the first time in 40 years. The number and proportion of patients with functioning kidney grafts is increasing, reaching 30% in 2011.

Therapy with renin-angiotensin-aldosterone system (RAAS)-blocking drugs prevents the development of fibrosis and angiogenesis in animal models and humans. In our study we have evaluated the systemic effect of RAAS blockade and the effect on peritoneal growth factors, cytokine production and membrane transport characteristics in patients on peritoneal dialysis. Thirty-seven peritoneal dialysis (PD) patients were enrolled in our cross-sectional study. Aldosterone and angiotensin II concentrations were measured in serum to determine the RAAS activity. The inflammatory and profibrotic activity was evaluated by measuring the concentration of C-reactive protein (CRP), serum albumin, and peritoneal concentration of interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), plasminogen activator inhibitor-1 (PAI-1), transforming growth factor-β (TGF-β) and cancer antigen-125 (CA-125). The transport characteristics of the peritoneal membrane were analyzed with a peritoneal equilibration test (PET). Results were compared between the group with RAAS-blocking drugs (RAAS group) and the group without them (non-RAAS group). Mean serum aldosterone concentration was significantly lower in patients treated with ARB-blocking drugs (P = 0.001) and serum angiotensin II concentration was lower in patients treated with ACE inhibitors (P = 0.009). RAAS blockade resulted in lower peritoneal PAI-1 levels (748.1 to 1222.7 ng/L; P = 0.07) without any influence on CRP, peritoneal concentrations of IL-6, VEGF, TGF-β and CA-125, or alteration in peritoneal membrane characteristics tested by PET. RAAS-blocking drugs could be effective in preventing peritoneal fibrosis due to possible reduction of peritoneal PAI-1 concentrations that have already been etiologically linked with fibrin deposition in the pathogenesis of encapsulating peritoneal sclerosis.
